а с какой радости должно совпадать если ты так пишешь?


FILE* fp;
time_t ctime;

ctime = time(0);
printf("Current time: %d\n", ctime);

fp = fopen("time.bin", "w");
fwrite( &ctime, sizeof(ctime), 1, fp);
fclose(fp);

ctime = 0;
fp = fopen("time.bin", "r");
fread( &ctime, sizeof(ctime), 1, fp);
printf("Current time (from file): %d\n", ctime);
fclose(fp);
